Reaktionsschritte

A suspension of 0.338 mg (1 mmol) of 7-iodo-2-methyl-4-pyrrolidin-1-yl-quinoline, 0.81 g (8 mmol) of trimethylacetamide, 0.414 g (3 mmol) of potassium carbonate (water free) and 20 mg (0.1 mmol) of copper (I) iodide in DMF (10 ml) was heated at 150° C. (oil bath temperature) under an argon atmosphere for 20 h. The reaction mixture was partitioned between EtOAc and water, the layers were separated, the organic layer washed twice with water dried over sodium sulphate and concentrated in vacuo. The residue was applied to silica gel column with CH2Cl2/MeOH/NH4OH (20:1:0.2) as eluent. Combination of the purified fractions and concentration in vacuo gave 175 mg (50.4%) of the desired 2,2-dimethyl-N-(2-methyl-4-pyrrolidin-1-yl-quinolin-7-yl)-propionamide as light brown solid. ISP mass spectrum, m/e: 312.3 (M+1 calculated for C19H25N3O: 312).
